European Equities a ‘Buy-One-Get-One-Free Market’

European equities could surprise to the upside this year, with earnings growth making it a "buy-one-get-one-free market," Peter Sullivan, head of European equity strategy at HSBC, told CNBC on Wednesday.

The first quarter earnings season had been "unambiguously good" in the U.S and was "pretty balanced" in Europe, he said.

"That sets us up for high single-figure earnings growth this year in Europe, and maybe slipping into double figures in the U.S. That's pretty far above consensus… so we've got to a very interesting and unusual point where we might actually get some positive earnings surprises coming through."

Sullivan highlighted that earnings growth since 2000 had almost doubled, but that prices had remained at similar levels.

But Sullivan warned that equity markets would see serious volatility when central banks confirm the end of their bond purchase programs.

Minutes of the Federal Reserve's latest meeting, released last week, revealed that a number of officials were open to tapering the bank's quantitative easing program next month. While on Tuesday, Pimco warned against assuming that the incoming governor of the Bank of England, Mark Carney, would expand monetary policy in the U.K.

"Just look at how extraordinary policy is," Sullivan added. "We've got interest rate numbers going back to 1694 in the U.K. and we're at a low - Isaac Newton was alive back then."

"It's asking a lot of policy makers to get out of this amazing, extraordinary position without some hiccups on the way. We should expect that – that's going to come straight through to the equity market. But we see that as volatility, not as the base case that there will be long-lasting error," he said.
